Calabrese Sprouting Broccoli: A Guide for Home Gardeners
Introduction
Calabrese sprouting broccoli is a popular choice among gardeners for its ease of care and versatility in the kitchen. This Italian heirloom has been cultivated in the Mediterranean region for centuries, but it gained commercial popularity in the United States after World War II.
What is Calabrese Broccoli?
Calabrese broccoli is a variety of broccoli known for its bluish-green heads and multiple side shoots. It is a cool-season crop that can be grown in early spring or fall. The central heads, which measure about five inches in diameter, are ready for harvest in 60 to 90 days. Calabrese broccoli is a member of the Brassicaceae family and is believed to contain cancer-fighting substances.
Growing Calabrese Broccoli
Starting Seeds Indoors:
To prevent spring-planted Calabrese broccoli from flowering prematurely during summer harvest, start seeds indoors six to eight weeks before the last frost. Sow seeds 1/4 inch deep in a good-quality starter soil and keep moist during germination. Provide plenty of sunlight or use grow lights to encourage seedling growth.
Hardening Off:
Before transplanting broccoli seedlings outdoors, they need to be hardened off to gradually expose them to full sunlight and wind. Place the seedlings outside for a few hours each day, gradually increasing the exposure time. This process helps prevent transplant shock and sun-scorched leaves.
Transplanting Outdoors:
Once the ground has warmed sufficiently and the danger of frost has passed, transplant Calabrese broccoli seedlings to a sunny location with well-drained soil. Rotate crops to prevent disease transmission. Avoid planting broccoli in areas where other members of the cabbage family have been grown within the last three years.
Fall Crops:
Fall crops of broccoli can be started in midsummer by directly seeding into the garden. Thin or transplant broccoli seedlings to space plants 12 to 16 inches apart. Keep the soil moist and control weeds by mulching or removing unwanted plants.
Calabrese Broccoli Pests
Like many members of the cabbage family, broccoli can attract unwanted pests. Common pests to watch out for include:
- Aphids
- Cabbage caterpillars
- Cabbage loopers
- Cabbage root flies
- Cutworms
- Diamondback moth
- Fleabeetles
To control pests, consider using row covers, spraying insecticides, or manually removing insects.
Harvesting Calabrese Broccoli
Harvest broccoli by cutting the main flower stem six inches below the head. Use a sharp knife to avoid damaging the plant. For the best quality, harvest the heads when the buds are tightly closed.
Uses of Calabrese Broccoli
Calabrese broccoli is a versatile vegetable that can be enjoyed fresh, sautéed, or stir-fried. It can also be frozen for future use. Broccoli is a popular ingredient in many recipes, including salads, soups, and pasta dishes.
Health Benefits of Calabrese Broccoli
Calabrese broccoli is a nutrient-rich vegetable that offers several health benefits. It is a good source of vitamins A, C, and K, as well as fiber and antioxidants. Studies have shown that broccoli may help reduce the risk of certain types of cancer, improve heart health, and boost the immune system.
